Patented May 21, 1907.

Application led January 16, 1906. Serial No. 296,389.

T0 all whom t may concern:

Be it known that I, VILLIAM R. EICHEN- SER, a citizen of the United States of Amervented certain new and useful Improvements 1n Lubricators, of

pertains to make and use the same, reference being had to the accompanying drawings, forming a part hereof.

This invention relates to improvements in lubricators of the type shown in Letters-Patent No. 782,734 granted to me Februaryvll,

I 1905, and it consists in certain novel features hereinafter iirst fully described and then particularly pointed out in the appended claims.

In the annexed drawings, which fully illustrate my invention, Figure 1 is a side elevation showing the device applied to the wristpin and cross-head of an engine 5 Fig. 2 is a longitudinal section of the lubricator, and Fig. 3 is a detail tran verse section of the trough. Fig. 4 Shows a modiiication.

In carrying out the present invention, I attach to the cross-head, directly over its j ournal, a short vertical pipe, A, to which, near the upper end of the same, is secured one end of a conducting pipe, B, The opposite end of this pipe B communicates with the wristpin through a short vertical pipe, C, and a suitable coupling, as clearly shown and as will be readily understood. Within this pipe B, I fit a tube, D, provided at intervals with internal shoulders, E, arranged to arrest any backward flow of the lubricant. In the preferred form of the invention, these shoulders or stops are constructed by crimping or compressing the body of the tube so that on the side toward the wrist pin a face will be presented at a right angle to the axis of the tube while on the other side a tapered bore leading to a central opening in the Said face will be provided, as shown at F.

In the modiiied form shown in Fig. 4, the arresters consist of inclined plates, G, secured within the tube, the inclination beinO' from the side of the tube toward the outlet or wrist pin end of the same.

Secured to the upper end ofthe pipe A and to supports, H, I, erected upon the pipe B, is a trough or oil-receiver, J, which is provided in its bottom with openings, K, L, registering with the pipe A and with the support H, respectively, the said support II being holica, residing at Johnstown, in the county of Cambria and State of Pennsylvania, have inwhich the following is such a full, clear, and exact description as will enable others skilled in the art to which it aplow while the support I may be hollowf. or solid as may be most convenient. Between the openings K and L, I secure a transverse partition, M, in the trough and the upper edges of the side walls of the trough are provided with inwardly and downwardly proj ecting flanges, N, which extend to the medial line oi the troughand have their inner edges arranged one above the other so as to present a small opening through which the oil may pass into the trough. When the parts are assembled, the partition M will be arranged directly over the cross-head and the portion of the trough extending toward the wrist pin will be about ive times as long as the other portion, experience having shown that the wrist pin requires about ive drops of oil to one drop for the cross-head. The oil or other lubricant is supplied from a cup, O, support-v ed by a standard P on any convenient part of the frame of the engine, the cup being arranged atabout the central point of the travel of the partition M.

The operation will be readily understood. The oil is permitted to escape from the oil cup at the speed best adapted for the successful and economical supply of lubricant to the bearings and drops therefrom into the oil receiver or trough whence it passes through the connecting pipes A and B to the bearings. The trough will be equal in length to the stroke of the engine so that oil will be caught therein in all positions of the pitmanand the feed of the oil consequently be continuous. The receiver or trough forms a reservoir or source of constant supply of oil so that oil will be fed to the bearings even during the very short interval needed to replenish the main supply in the oil cup. The iianges on the inner Sides of the walls of the trough effectually prevent oil splashing from the trough so that there will be no waste of oil. The oil-arresters in the tube D constitute pockets which catch the baclnvardly-lowing oil and thereby create a supply throughout the length of the said tube in order that oil will be maintained constantly close to the wrist pin and there will be no cessation of the lubrication caused by the travel of the oil along the pipe B.

It will be readily understood fromiifthe drawings considered in connection with the foregoing description, that the oil for the cross-head passes almost directly to the same while the oil for the wrist-pin is caused to flow thereto through the pipe B as the pin IOO descends while on the upward movement of there being flanges at the upper edges of the the pin the oil will tend to flow backward. trough extending inward tothe medial line This backward movement is counteracted by thereof and having the edges out of contact. the oil-arresters so that the oil be held to- 3.
